No, you wouldn't go to a nosologist if you have nose trouble. The term
for the branch of medicine that deals with the ear, nose, and throat is
otorhinolaryngology (or otolaryngology). You have to use all three to
pronounce it.

"Marvin's Room is so loaded up with terminal illness that it has
as much nosology as narrative: there are paralysing strokes, mental
illness, asphyxiation, leukaemia, senility and chronic back pain.
Even the doctor's receptionist is on lithium. But above all, there's
the Big C -- Crying."

Evil is like a shadow - it has no real substance of its own, it is simply a
lack of light. You cannot cause a shadow to disappear by trying to fight
it, stamp on it, by railing against it, or any other form of emotional or
physical resistance. In order to cause a shadow to disappear, you must
shine light on it. -Shakti Gawain, teacher and author (b. 1948)
